Abstract

A network control device. The wireless communication module receives a plurality of first signals, wherein each first signal includes information about a preferred transmission beam in the first beam class determined by the communication device. Based on the received first signal, the controller selects a group of communication devices to participate in one-to-many beam training, and selects one or more transmission beams in the second beam class for training. The group of communication devices have the same preferred transmit beam in the first beam class, and the selected one or more transmit beams in the second beam class are associated with the preferred transmit beam in the first beam class. The wireless communication module also sequentially transmits signals using the selected one or more transmit beams to perform one-to-many beam training for simultaneously training the selected one or more transmit beams in a second beam class among the group of communication devices. beam.

Description

[0001] Cross References to Related Applications [0002] This application claims U.S. Provisional Application No. 61 / 993,576, filed May 15, 2014, titled "Method for Efficient Transmit Beam Training in Wireless Systems," and U.S. Application No. 14 / 706,098, filed 2015 priority date of May 7, 2011, the entire contents of which are incorporated by reference into this application. technical field [0003] The present invention relates to efficient beam training methods, and more particularly, to one-to-many hierarchical beam training methods. Background technique [0004] The term "wireless" generally refers to electrical or electronic operation that is not accompanied by the use of a "hard-wired" connection. "Wireless communication" is the transmission of information over a distance without the use of electrical conductors or wires. The distances involved can be short (a few meters for a TV remote control) or very long (thousands or even millions of kilometers for wireless c...
